The Atmospheric Chemistry Group in the Department of Environmental Systems Science invites applications for a PhD student position. In a collaboration with SECO and SUVA within the national inspections campaign of chemicals at work, the research project aims at improving the assessment of occupational exposure to hazardous volatile chemicals in complex mixtures used in industrial and professional sectors.
Many chemical products used at workplaces, such as paints, lacquers or lubricants contain hazardous volatile components, which upon inhalation may lead to associated health risks. In general, exposure levels to vapors depend on the specific use of the chemical product (e.g. temperature, type of application), and the physicochemical properties of the components (e.g. solubility, miscibility, and volatility). For instance, when the operating temperature leads to evaporation of some less hazardous components, the concentration of the remaining more hazardous ones is increased, which in turn may increase their volatility and lead to increased inhalation hazards. Or, when a product is reactive, the mixture composition changes with time, which influences the activity coefficients of all components. Therefore, to examine inhalation risks the type of application and the interactions of the components with each other need to be considered.
The main tasks of the PhD student will be:
The start of the project is as soon as possible.
The successful candidate should hold an MSc degree (or equivalent) in environmental sciences, chemistry or chemical engineering with good knowledge of thermodynamics and interests in programming languages such as Python, Java or Fortran. We are looking for a highly motivated, committed, and creative person. Good writing and oral communication skills in English are required.
We look forward to receiving your online application that includes a CV, academic transcripts, work certificates (if any) and a 1-page motivation letter stating research experiences and interests. Please provide the contact information of at least two potential referees. Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered.
